iPhone 3G “unable to join the network” wifi error
Further to an early post whereby my iPhone 2G had issues connecting to wi-fi networks after a firware update, a similar thing happened to my iPhone 3G last week for no apparent reason.
My iPhone 3G wouldn’t connect to my TimeCapsule wi-fi. I rebooted the TimeCapsule and the iPhone but it still gave an error. I then tried with my 2nd home wi-fi network (Netgear DG384GT) and the same “unable to join the network” error message popped up. In case it was an issue with channel interference or WEP password mistakes I switched channels and turned all security off temporarily. This still didn’t solve anything, my MBPro, Air, AppleTV, Xbox etc could still connect perfectly as did my old iPhone 2G. I backed up my iPhone and then carried out a full restore but even the virginal factory fresh restored software refused to connect. Once a friend with another 3G came round and connected without a problem I had little choice but to book an appointment at Apple’s Genius bar.
The Genius tried to connect to the stores wi-fi and it failed, he checked the phone had the latest version, did a force reboot (I’d already done several) and then simply said “I’ll go and get you a new one”.
After checking for liquid damage using an otoscope to view the liquid damage indicators in the headphone socket and bottom port he gave me a new iPhone 3G and I was on my way.
Since I use MobileMe & Exchange PUSH, when I set up the accounts quickly on store on the new iPhone my contacts were pulled down onto the iPhone in under a minute which is useful since my iPhone backup was on my home machine a few hours away.

It seems that it could be a hardware problem.I held my iphone touching the antenna of WIFI router, it connected to the router. I was able to use the internet in this position only. Moving away from router’s antenna, internet does not works. At leaset now I can do some very urgent works on iphone without GPRS connection.I was not able to use my wifi for last six months. Done everything that was already discussed in all the forums.I am calling it solved only because, I was afraid of future unlocks will not be possible without WIFI. Uptil 3.1.2 “iphone pcsuite” could be used to install ultrasn0w directly through PC. But from 3.1.3 iphone needs to install “AFC2ADD” through cydia, before it can be recognised as a jailbreaked iphone. Atleast WIFI working. This way I can update important cydia updates and apps without having to use GPRS.
